> Listen queue size is greater than the system max net.core.somaxconn (128)解决
'''
uwsgi的配置文件中的listen的值设置太大了，超过系统默认值128，报错
修改/proc/sys/net/ipv4/tcp_max_syn_backlog /proc/sys/net/core/somaxconn这两个文件，重启又会复原
Linux中可以工具syctl来动态调整所有的kernel参数 # sysctl -a
修改参数值的语法 # sysctl -w net.core.somaxconn=65535   改动虽然可以立即生效，但是重启机器后会恢复默认值
永久保留改动，需要用vi在/etc/sysctl.conf中增加一行
net.core.somaxconn= 65535
然后执行命令
# sysctl -p
